Facebook has announced the expansion of their alliance with antivirus companies in hopes to better secure its users and promote good privacy… here is a quick scope of the details:

Today, we are excited to announce the expansion of our AV Marketplace to include 7 new partners to our growing coalition of security companies. Starting now, Facebook users will be able to download software from – avast!, AVG, Avira, Kaspersky, Panda, Total Defense, and Webroot. Not only do we have new partners but also many of our existing partners – Microsoft, McAfee, Norton, TrendMicro, and Sophos – will begin offering anti-virus software for your mobile devices. You can visit the AV Marketplace now to download your free anti-virus software for PC, Mac and Mobile.

Our new anti-virus partners bring with them both the latest software and comprehensive intelligence. As with our existing partners, these seven companies will help protect Facebook’s community of over a billion users by improving our URL blacklist system. This system scans trillions of clicks per per day, and before each click, the system consults the databases of all our AV Marketplace partners to make sure the website you are about to visit is safe. This means that whenever you click a link on our site you are protected both by Facebook and 12 of the industry leaders in computer security. We will be cooperating with these partners more in the future, and look forward to announcing new tools soon.
